Abstract

The invention discloses a gridding real-time monitoring method for total electron content of an ionized layer. The gridding real-time monitoring method for the total electron content of the ionized layer comprises the steps of firstly using data of a plurality of reference stations in a continuous operation reference station network to build a whole day ionized layer delay polynomial model, and resolving a receiver hardware delay of the day before and a satellite hardware delay of the day before; and then using the receiver hardware delay of the day before and the satellite hardware delay of the day before to correct the total content of electron concentration of the ionized layer on a satellite propagation path on the day of monitoring according to a characteristic that the receiver hardware delay and the satellite hardware delay are stable, and building a single epoch multi-station polynomial model to monitor changes of the total electron content of the ionized layer in the zenith direction of a grid point after gridding in real time. Experiment results of all epochs in a whole day indicate that inner coincidence precision of the gridding real-time monitoring method for the total electron content of the ionized layer is averagely superior to 1TECU, and outer coincidence precision of the gridding real-time monitoring method for the total electron content of the ionized layer is averagely 1TECU.

Description

technical field [0001] The invention belongs to the field of atmospheric change monitoring, in particular to a real-time monitoring method for the total electron content of the ionosphere. Background technique [0002] As an important part of the sun-terrestrial space environment, the ionosphere has an important impact on modern radio engineering systems and human space activities. The study of the ionosphere is both complex and meaningful. The study of the ionosphere is not only conducive to understanding the ionosphere itself, finding ways to overcome the possible disasters caused by the ionosphere, and exploring ways to use the ionosphere for the benefit of mankind, but also helps to promote the field of earth science. Research and development of relevant ionospheric theory and application issues. After the advent of the Global Positioning System (GPS), due to its advantages of high precision, high reliability, large amount of data, all-round, all-weather and continuous ...
